2009-06-16NLS: update handling of UnicodeAlan Stern1-2/+2
This patch (as1239) updates the kernel's treatment of Unicode. The character-set conversion routines are well behind the current state of the Unicode specification: They don't recognize the existence of code points beyond plane 0 or of surrogate pairs in the UTF-16 encoding. The old wchar_t 16-bit type is retained because it's still used in lots of places. This shouldn't cause any new problems; if a conversion now results in an invalid 16-bit code then before it must have yielded an undefined code. Difficult-to-read names like "utf_mbstowcs" are replaced with more transparent names like "utf8s_to_utf16s" and the ordering of the parameters is rationalized (buffer lengths come immediate after the pointers they refer to, and the inputs precede the outputs). Fortunately the low-level conversion routines are used in only a few places; the interfaces to the higher-level uni2char and char2uni methods have been left unchanged.

2009-06-12Sanitize ->fsync() for FATAl Viro1-2/+2
* mark directory data blocks as assoc. metadata * add new inode to deal with FAT, mark FAT blocks as assoc. metadata of that * now ->fsync() is trivial both for files and directories Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2009-06-03FAT: add 'errors' mount optionDenis Karpov1-1/+1
On severe errors FAT remounts itself in read-only mode. Allow to specify FAT fs desired behavior through 'errors' mount option: panic, continue or remount read-only. `mount -t [fat|vfat] -o errors=[panic,remount-ro,continue] \ <bdev> <mount point>` This is analog to ext2 fs 'errors' mount option.

2008-11-12fat: drop negative dentry on rename() pathOGAWA Hirofumi1-1/+1
Drop the negative dentry on rename() path, in order to make sure to use the case sensitive name which is specified by user if this is for creation. For it, this uses newly added LOOKUP_RENAME_TARGET like LOOKUP_CREATE. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
2008-11-07fat: Kill d_invalidate() in vfat_lookup()OGAWA Hirofumi1-7/+6
d_invalidate() for positive dentry doesn't work in some cases (vfsmount, nfsd, and maybe others). shrink_dcache_parent() by d_invalidate() is pointless for vfat usage at all. So, this kills it, and intead of it uses d_move(). To save old behavior, this returns alias simply for directory (don't change pwd, etc..). the directory lookup shouldn't be important for performance.

2008-11-07fat: Fix/Cleanup dcache handling for vfatOGAWA Hirofumi1-44/+80
- Add comments for handling dcache of vfat. - Separate case-sensitive case and case-insensitive to vfat_revalidate() and vfat_ci_revalidate(). vfat_revalidate() doesn't need to drop case-insensitive negative dentry on creation path. - Current code is missing to set ->d_revalidate to the negative dentry created by unlink/etc.. This sets ->d_revalidate always, and returns 1 for positive dentry. Now, we don't need to change ->d_op dynamically anymore, so this just uses sb->s_root->d_op to set ->d_op. - d_find_alias() may return DCACHE_DISCONNECTED dentry. It's not the interesting dentry there. This checks it. - Add missing LOOKUP_PARENT check. We don't need to drop the valid negative dentry for (LOOKUP_CREATE | LOOKUP_PARENT) lookup. - For consistent filename on creation path, this drops negative dentry if we can't see intent.

2008-11-07vfat: Fix vfat_find() error path in vfat_lookup()OGAWA Hirofumi1-5/+13
Current vfat_lookup() creates negetive dentry blindly if vfat_find() returned a error. It's wrong. If the error isn't -ENOENT, just return error.

2008-11-07fat: Fix and cleanup timestamp conversionOGAWA Hirofumi1-2/+3
This cleans date_dos2unix()/fat_date_unix2dos() up. New code should be much more readable. And this fixes those old functions. Those doesn't handle 2100 correctly. 2100 isn't leap year, but old one handles it as leap year. Also, with this, centi sec is handled and is fixed.
