4605 5658 d 1 h decky /branches/snapshot/ add task snapshoting branch  
4593 5660 d 23 h decky /trunk/uspace/srv/vfs/ avoid unaligned memory access  
4587 5661 d 17 h jermar /trunk/uspace/ Implement stat() and VFS_IN_STAT.
Modify bdsh() to use stat() during ls.
In devfs, allow lookups that don't
specify one of L_FILE and L_DIRECTORY.		  
4585 5661 d 20 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4584 5662 d 1 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4566 5664 d 18 h jermar /trunk/uspace/srv/vfs/ Do not use the "pending" fibril mechanism in VFS  
4555 5672 d 17 h jermar /trunk/uspace/srv/vfs/ Finish converting VFS to fibril synchronization.  
4551 5672 d 18 h jermar /trunk/uspace/srv/vfs/ Handle each VFS request using a dedicated connection.  
4539 5674 d 20 h jermar /trunk/uspace/srv/vfs/ Handle pending mounts using only one fibril.  
4520 5679 d 20 h jermar /trunk/uspace/srv/vfs/ Synchronize access to pending_req.  
4518 5680 d 17 h jermar /trunk/uspace/srv/vfs/ Make VFS use the new synchronization for fibrils. Now there should be no (or
only secondary) fibril serialization. Code reorganized not to hold the phone
lock during async_wait_for() in most cases. Tested on ia32. On amd64, VFS
crashes, but I think it is an unrelated problem.		  
4509 5682 d 1 h decky /trunk/uspace/ rename libadt -> adt  
4463 5686 d 20 h decky /trunk/uspace/srv/vfs/ VFS rewrite:
- add new VFS methods
- VFS_NODE for getting VFS node for a file descriptor
- VFS_OPEN_NODE for opening an i-node directly
- VFS_DEVICE for getting the underlying device of a file (if any)
- VFS_SYNC for syncing buffers
- L_OPEN flag is set to underlying filesystem in VFS_LOOKUP when opening a file to support initialization (if any)
- VFS_CLOSE is now propagated to underlying filesystem to support cleanup (if any)		  
4445 5688 d 22 h decky /trunk/uspace/srv/vfs/ revert commit 4443 and implement a much finer solution as suggested by Jakub Jermar in commit 4444  
4443 5691 d 21 h decky /trunk/uspace/srv/vfs/ serialization of VFS_OPEN implementation to avoid lockup by concurrent open() operations from multiple tasks  
4437 5693 d 5 h jermar /trunk/uspace/srv/vfs/ Fix function definition.  
4431 5697 d 23 h jermar /trunk/uspace/srv/vfs/ Hold the namespace rwlock during the entire operation of vfs_mount_internal().
Get rid of rootfs futex, which is not needed anymore.
Do not instantiate VFS node for the mounted root if the mount failed.		  
4427 5699 d 19 h jermar /trunk/uspace/srv/vfs/ Fix rename() on a non-root file system.  
4409 5701 d 17 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4368 5712 d 6 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.
