3521 5741 d 2 h jermar /trunk/uspace/ Move libfs_blockread(), block_get() and block_put() to libblock.  
3519 5741 d 4 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_node_sync().  
3518 5741 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add comments to functions in fat_fat.c.  
3517 5741 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add FAT allocation futex.  
3516 5741 d 6 h jermar /trunk/uspace/srv/fs/fat/ Pass the buffer holding the boot sector to the internal functions so that it
doesn't have to be block_get()'ed in each function. The idea is that the boot
block should be read by the top-level functions in fat_ops.c and passed down the
call chain.		  
3513 5741 d 23 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_append_clusters().  
3512 5742 d 0 h jermar /trunk/uspace/srv/fs/fat/ Make sure that data are converted from / to the native endianity when writing them
out to / reading them in from the file system.		  
3510 5742 d 1 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_mark_cluster().  
3507 5742 d 3 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_alloc_shadow_clusters().  
3506 5742 d 5 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to manipulatings file allocation tables to fat_fat.c.  
3505 5742 d 6 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to FAT dentries to fat_dentry.c.  
3504 5742 d 6 h jermar /trunk/uspace/srv/fs/fat/ Prepare to break fat_ops.c into multiple files.  
3503 5742 d 7 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_alloc_clusters().  
3501 5742 d 23 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_fill_gap().  
3500 5743 d 1 h jermar /trunk/uspace/srv/fs/fat/ More complete prototype of fat_write().  
3499 5743 d 4 h jermar /trunk/uspace/srv/fs/fat/ Mark progress in fat_write().  
3497 5743 d 8 h jermar /trunk/uspace/srv/fs/fat/ Dummy fat_write().  
3352 5806 d 23 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3335 5810 d 22 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5813 d 23 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.		  
3314 5814 d 23 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5815 d 0 h jermar /trunk/uspace/srv/fs/fat/ When removing a FAT node from the ffn list, use the correct pointer instead of
an uninitialized one.		  
3308 5816 d 22 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5817 d 0 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5818 d 20 h jermar /trunk/uspace/srv/fs/fat/ FAT dentry type used for subdirectories doesn't store the directory size in the 'size' field.
Introduce a simple workaround that will let us have 64 directory entries at maximum.		  
3272 5819 d 10 h jermar /trunk/uspace/srv/fs/fat/ Several fixes for the FAT file system:
- do not copy padding during file name canonization
- properly nul-terminate the FAT file name during canonization
- compare FAT file name and the component name case insensitively
- block_get() takes a block offset, not byte offset as parameter		  
3257 5820 d 9 h jermar /trunk/uspace/srv/fs/fat/ First attempt at delivering the FAT16 read-only support.
Needless to say it doesn't work yet, but now it's only
the lurking bugs that need to be fixed.		  
3253 5821 d 21 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3252 5821 d 22 h jermar /trunk/uspace/ Add a comment to libfs_blockread() and change type from size_t to off_t at
various places.		  
3251 5822 d 0 h jermar /trunk/uspace/ Move tmpfs_blockread() to libfs and rename it to libfs_blockread().
Add one argument to specify block size.		  
3250 5822 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Let tmpfs_blockread() use async_req_2_1() instead of ipc_call_sync_2_1().  
3247 5823 d 0 h jermar /trunk/uspace/srv/fs/tmpfs/ Avoid magic numbers in tmpfs_dump.c.  
3201 5857 d 5 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5883 d 4 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5883 d 22 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5883 d 22 h jermar /trunk/uspace/srv/fs/fat/ Initialize global FAT IDX structures when the FAT server starts and initialize
per-file system FAT IDX structures when a file system gets mounted.		  
3109 5884 d 4 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.		  
3103 5884 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Evict the code which loads the TMPFS file system from a file system dump to a
dedicated source file.		  
3091 5886 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Return value argument to ipc_call_sync_X_Y() may not be int or it will
break on 64-machines that are sensitive to unaligned memory accesses.
Moreover, overcasting int * to sysarg_t * is not a good idea either
even if the int is by chance aligned on a 64-bit boundary as some
unknown memory will get overwritten during the assignment. Change the
type of the retval argument to ipcarg_t.		  
3087 5887 d 4 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk
