[PATCH V2] xfsprogs: cosmetic changes to libxfs_inode_alloc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This pre-patch helps make the next libxfs-sync for 5.11 a bit
more clear.

In reality, the libxfs_inode_alloc function matches the kernel's
xfs_dir_ialloc so rename it for clarity before the rest of the
sync, and change several variable names for the same reason.

V2: Fix up local transaction pointer problems pointed out by Brian.

Essentially, use tp locally, and reassign tpp on return.
