2012-09-17fs/jfs: TRIM support for JFS FilesystemTino Reichardt1-0/+1
This patch adds support for the two linux interfaces of the discard/TRIM command for SSD devices and sparse/thinly-provisioned LUNs. JFS will support batched discard via FITRIM ioctl and online discard with the discard mount option.

2011-06-20jfs: agstart field must be 64 bitsDave Kleikamp1-1/+1
The previous patch added the agstart field to jfs_ip, but declared it a long. We need to make sure its 64 bits on every platform. Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
2011-06-20JFS: Don't save agno in the inodeDave Kleikamp1-1/+2
Resizing the file system can result in an in-memory inode being remapped to a different aggregate group (AG). A cached AG number can cause problems when trying to free or allocate inodes. Instead, save the IAG's agstart address and calculate the agno when we need it. Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>

Removed trailing spaces & tabs, and spaces preceding tabs. Also a couple very minor comment cleanups. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> (cherry picked from f74156539964d7b3d5164fdf8848e6a682f75b97 commit)
2006-03-09JFS: add uid, gid, and umask mount optionsDave Kleikamp1-0/+5
OS/2 doesn't initialize the uid, gid, or unix-style permission bits. The uid, gid, & umask mount options perform pretty much like those for the fat file system, overriding what is stored on disk. This is useful for users sharing the file system with OS/2. I implemented a little feature so that if you mask the execute bit, it will be re-enabled on directories when the appropriate read bit is unmasked. I didn't want to implement an fmask & dmask option.

2006-01-09[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen1-2/+2
This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+197
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
