Re: [LTP] [PATCH 1/4] libswap: add known swap supported fs check

[Petr Vorel <pvorel@suse.cz>]

Hi Li,

> This introduce an enhancement to the library's is_swap_supported
> function to check for filesystem compatibility before attempting
> to create and enable a swap file.  A list of supported filesystems
> is added (ext2, ext3, ext4, xfs, vfat, exfat, ntfs), and a check
> against this list is performed to ensure that the swap operations
> are only attempted on known compatible filesystems.

> If the make_swapfile function fails, the error handling is now
> more descriptive: it distinguishes between failures due to the
> filesystem not supporting swap files and other types of failures.
> Similarly, when attempting to enable the swap file with swapon,
> the patch ensures that clearer error messages are provided in
> cases where the operation is not supported by the filesystem.
