2699 5975 d 12 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2698 5975 d 17 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2697 5978 d 22 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2696 5979 d 2 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2695 5979 d 2 h decky /trunk/contrib/conf/ make msim.conf compatible with MSIM 1.3.x  
2694 5980 d 15 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 5980 d 22 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2692 5982 d 17 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2691 5984 d 15 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
 
2690 5985 d 13 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2689 5985 d 14 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 5985 d 14 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 5985 d 15 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 5985 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 5985 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2684 5987 d 16 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2683 5987 d 19 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
 
2682 5987 d 21 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 5987 d 22 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 5987 d 22 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
